Specification of Letters Patent. Patented J 11119 1915 Application filed June 28, 1912. Serial No. 706,383.

To all whom it may concern Be it-known that I, LOUIS 1V. SOUTHGATE, a citizen of the. United States, residing at Vorcester, in the county of TVorcester and State of Massachusetts, have invented a new and useful Paper-finding Mechanism, of 'which the following is a specification.

The object of this invention is to provide a new and improved paper winding mechanism by which a web of paper can be accurately wound into a roll.

The device has been primarily designed for use in connection with the perforated note-sheets'empl'oyed in musical instruments so that by accurate drawing forward and winding of said note-sheet the same can be kept in accurate registration with the tracker bar. v

The best way'now known to me for practising the invention is shown .in the accompanying drawing in which,

Figure 1 is a front elevation of the spool box of a musical instrument showing myinvention' applied to the winding or Itake-up roll, therein, Fig. 2 is an end elevation of one of the flanges ,on the take-up spool, Fig. 3 is a detail view on an enlarged scale illustrating the operation of the cam on said flange, and Fig. 41 is an enlarged view illustrating the operation of the throw-out connections.

Referring to the drawing and in detail, A designates the spool box and BB the usual hearings in which can be placed a music spool or roll C upon which is wound a perforated note-sheet D.

E designates the usual tracker having music openings, which tracker is secured to the spool box.

The take-up spoolmechanism is constructed as follows :10 designates a shaft which is journaled in the spool box and on which the body F of the take-up spool is mounted and pinned thereto by a pin 11 so that the take-up spool and said shaft turn as one piece. Secured on said shaft 10 is a gear '12. A supplemental frame or gear support 13 is secured to the spool box by studs or bushings. A shaft 14is slidably journaled in he side of the spool box and in said frame 13 and carries a pinion 15 at its end which can mesh with the gear 12 on the shaft 10. The

' shaft 14 is provided with asprocket wheel 16 the two flanges being rights and ,lefts.

at its end which is driven from'the motor and a sprocket wheel 17 is loosely journaled on the shaft 1% and connects by a sprocket chain 18 to a sprocket pinion 19 secured on the shaft,

of the right-hand journal B for the music roll. The sprocket wheel 17 carries a pin 20 set in position to be engaged by a pin 21 carried by a grooved collar. 22 secured on the shaft 14 engaging which is apin projecting from a pivoted lever 23. A link 24 extends from the lever 23 to the usual rewind controlling finger lever. This gearing is of the ordinary or preferred arrangement and-is so at a fast speed in a direction todraw the notesheet back overthe tracker and from on the music spool. 1

As thus far described, the parts are of the usual or approved construction. The particular feature of the invention resides in the constructionof the flanges on the takeup spool, which construction will now be described. This construction is preferably duplicated at both ends of the take-up spool,

the take-up spool F and rewind the same description "of 'the right-hand flange construction will give a clear understanding of the invention.

Fitted on a cut-away portion at the end of the music spool is a flanged end piece 25 which is held to the music spool F by screws 26. V I

G represents the music spool flange. The same has a relatively long hub 27 whichis loosely fitted on the shaft 10 and which extends through the end piece 25 and into a hole or socket bored in the end of the takeup spool. A spring 28 is placed on this hub and has one end bearing on the end piece 25 and the other on a collar 29 secured on said hub 27. The end piece 25 is provided with projections 30 fitted into holes 31 out in the end flange G. By this arrange- "sheet D and the; flange. is normally heldnicnt the endflange G willhave to turn F l'ffand the end flange can with the. spa

pendently of thespool F pushed-intoward the spool by .thelaction ofgthepring 28. V v 1,. The body of the-spool ismade of a'length just a little'less than; the width of the note away froliiengagement withthe' edge of the note-{sheet and from that portion of thefnotesheet. wound on the take-up spool, but is allow'edto move inwardly for 'a shortperiod during each rotation of the takeaipspoolto pat or. adjust each convolution-of the note? sheet as is wound on the take-up spool and thus insure a complete accurate winding. To accomplishthis function, the take- ..up 'spooljis provided with a or cam surface 32, engaging which is a screw 33 threaded in an arm 34:;secured'ona shaft 35.

v A check; nut 330- is preferably mounted on the screw 33 so'tli'at thesame can be kept in accurate adjustment.-' By -reason Cofthis volve, as the canijsu-riace 32 comes opposite place for each :revolu ;-'Iheconstructionis; jduplicated'at the left hand end I.-o f the spool; the shaft in this. part of the s'trueture 'eing'ijournaledlinthe' spool box and. secu'red inside of the spooL- i tak ;up s'pgql, fla ng "';movable ax- I The cams on the two flanges G G arepref- 'erably set in theisame horizontal. line so that they" will act simultaneously, or together.

,VVhile I havelshown theiflange construction duplicated at each end of the take-up spool,',it;is to'be understood, bfcourse, that setin position the broad invention .-con'templates the "use.

of only one operating-or movable flange, say

the right-hand flange.- WVhen this single "flange arrangement is employed, the lefthand flange is ma e'p'e'rm'anent or -fixed and right-hand side of the spool boxfand "is. provided with an arm 36 which connects by a link 37-h; lever 38 turnmgwrth, or formed flanges G so that the flanges will close up to the note-sheet as the sameis rewound on the music spool, and .so that the operation. 69-

' f The shaft 3'5 is 7 extended through the lay this arrangcznent by insuring accucurate registration with -the tracker during.

v tion of-the music-sheet and thetracker can be obtained. I

\Vhile theinventionhas' been-described as applied to a perforated note-sheet in'a musical instrument, the same is capable of broader application and can beused in other structures wherefit is desired to wind at web of paper accu rately, into ,a roll. '1 The details 'andarrangements herein shown and described-may be greatlyvaried by a skilled mechanic without, departing from the scope of the invention'as'expres'sed in the claims.
